V. I. Lenin delivered a short but impressive speech on
the significance of Karl Marx as a socialist leader.

“The working people were enslaved, despite political liberties. Now
they are moving towards the workers’ revolution, which will create a
socialist society without landowners and capitalists. To Russia has fallen
the great honour and joy of helping to establish this socialist society and
a world Soviet Republic. Today, on this international festival of labour,
when we wish to prove to everybody that we shall succeed in coping with the
task of organising a socialist society of the working people, we honour the
memory of Karl Marx. And I am confident that the laying of this monument to
our great teacher will serve as a call impelling us to give all our
attention to the need for working hard and long to create a society in
which there will be no room for exploitation.”
